I apologize in advance PowerShell Noob here. I am trying to get a list of all computer objects that have contacted our DC over the past year. That part is easy, however do to the lack of naming schema we are unable to differentiate between servers and desktops. I would like to add the OS version to this report. Is the OS version of a stale object stored in AD? Would I need to poll the machines via PS remoting to pull this information?
